migrate to systemd-networkd

Make "systemd-networkd" manage your network interfaces (wired, in that case):

• delete/move /etc/network/interfaces

• stop and disable NetworkManager service, optionally, remove ifupdown package.

• create interface file:

  • using DHCP:

	# /etc/systemd/network/10-wired-dhcp.network
	[Match]
	Name=enp2s0

	[Network]
	DHCP=yes

	[DHCP]
	UseDHS=true

• for static configuration:

	# /etc/systemd/network/10-wired-static.network
	[Match]
	Name=enp2s0

	[Network]
	Address=10.1.10.9/24
	Gateway=10.1.10.1
	DNS=10.1.10.1

• start and enable systemd-networkd.service:

sudo systemctl start systemd-networkd.service
sudo systemctl enable systemd-networkd.service

• optionally, reboot the machine
